Google Documents-Revision History Interface

Official Google Enterprise Blog

In Google documents, they launched a new revision history interface which lets you easily see what changes have been made to a document. Changes are color-coded based on each collaborator, so it’s clear who did what. You can click on a time stamp in the right column to see what changes were made at a given time, or use the arrow keys to quickly scan through many revisions. To learn more about revisions history, see the Google Docs blog.
